I A Specification forming part of Letters Patent No. 23.,l2 6,- dated March v1,1859.

To all whom it'may concern:

. Be it known that we, AMOS G. THoMPsoN and ANDREW J. THOMPSON, of Bellville,-in the county of Richland and State of Ohio,

have invented a new and useful Machine for Planting Corn and other Seeds; and wefldo hereby declare that the following, is'ia full, clear, and exact description of the construction and operation of the same, reference bcinghad to the annexed d rawings, making part of this specification, in which 7 Figure lis a'perspective View. Fig. 2 isa detached section.v A A, Fig.1, is the main frame, to. which shafts '1) Dare permanently atta-ched by bolts right side'pieces of the main frame;

B B are plungers passing down behind the seed-hoppers, which plungers arepassed down ward by the operator pressing on the crossbarE, by means of which motion the seed is separated from the bulk of seed in the hopper and passed through the aperture through the plungers into the seed-chambers F F, as illustrated in Fig. 2, which cross-bar and plungers are thrown back to their proper position by spiral springs a a, and held in position by means of said springs and straps'o o.

"G G are gage and e'overingwheels, attached to main frame by stirrups 0 0, which wheels are operated upon by'means of spiral springs d d, the operation of which springs, in con-- junction with the permanent attachment of the shafts to thedraft-animal and the pressure of the hand of the operator upon the main frame, are designed to regulate-the depth of the shares H H, and at the same time gather a and slightly press the loose earth into thefur row and cover the seed. It is also'designed to use those wheels as a truck .-.carriage to j carry the machine from field to field, 8w. This is done by sliding the metal bolts passing through spiral springs (l d downward and placing the adjusting-pin below the fastening n at tomain irame. This operation places the wheels below the shares in such a manner as K to prevent them from coming in contact with the earth.

' To mark out the field before checking and CG are seed-hoppers attached to the up- Witnesses:

plantin'g, take off the wheels G G, spiral springs d d, and stirrups c c by detachingsaid stir rups- .from the main frame at their-fasteningbolts K K;jthen take off cross-bar E, plungers B B, and spiral springs a a by detaching straps o 0 that button on main frame," and the ma chine is ready'for use for that purpose.

Fig. 2 is ajdetached section, of which T is-a square cavity passing through the plunger B, through which cavity, when the plunger passes downward, the seed passes intothe seed-chainber F, and is there retained by the Ivalve'W, which is adjusted by spiral springs X, until i said plungers return againidownward, and the lowerend of said plunger, coming in contact with s'aidgde'p'osi-ted seed and valve, forces the valye openand deposits the seed in the fur- I row," and the seed for another-hillsis deposited inthe chamber by said downward motion, and so on at; each Succeeding movement of said Qof the brush should be cut square andextend out-, so as to slightly brush the side oithe plunger, and-should in all cases be made as Wide as the issuing-cavitythrough the pun] er. f is a gage in the plunger, designed for regulating the desired quantity of seed, 'lwhich gage is secured and regulated by a serene We 'claim- I The arrangement of spiral springs'a a, in combination with crossbar E and straps" 0 o,

for regulating the movement of the plungers B B, substantially as specified.
